    copied!<p>What are some good tools for getting a quick start for parsing and analyzing C/C++ code?</p> <p>In particular, I'm looking for open source tools that handle the C/C++ preprocessor and language. Preferably, these tools would use lex/yacc (or flex/bison) for the grammar, and not be too complicated. They should handle the latest ANSI C/C++ definitions.</p> <p>Here's what I've found so far, but haven't looked at them in detail (thoughts?):</p> <ul> <li><a href="http://cscope.sourceforge.net/" rel="noreferrer">CScope</a> - Old-school C analyzer. Doesn't seem to do a full parse, though. Described as a glorified 'grep' for finding C functions.</li> <li><a href="http://gcc.gnu.org/" rel="noreferrer">GCC</a> - Everybody's favorite open source compiler. Very complicated, but seems to do it all. There's a related project for creating GCC extensions called <a href="http://research.alexeysmirnov.name/index.php?area=sec&amp;proj=gem" rel="noreferrer">GEM</a>, but hasn't been updated since GCC 4.1 (2006).</li> <li><a href="http://ivs.cs.uni-magdeburg.de/~puma/" rel="noreferrer">PUMA</a> - The PUre MAnipulator. (from the page: "The intention of this project is to provide a library of classes for the analysis and manipulation of C/C++ sources. For this purpose PUMA provides classes for scanning, parsing and of course manipulating C/C++ sources."). This looks promising, but hasn't been updated since 2001. Apparently PUMA has been incorporated into <a href="http://www.aspectc.org/" rel="noreferrer">AspectC++</a>, but even this project hasn't been updated since 2006.</li> <li>Various C/C++ raw grammars. You can get <a href="http://www.sigala.it/sandro/software.php" rel="noreferrer">c-c++-grammars-1.2.tar.gz</a>, but this has been unmaintained since 1997. A little Google searching pulls up other basic lex/yacc grammars that could serve as a starting place.</li> <li>Any others?</li> </ul> <p>I'm hoping to use this as a starting point for translating C/C++ source into a new toy language.</p> <p>Thanks! -Matt</p> <p>(Added 2/9): Just a clarification: I want to extract semantic information from the preprocessor in addition to the C/C++ code itself. I don't want "#define foo 42" to disappear into the integer "42", but remain attached to the name "foo". This, unfortunately, excludes several solutions that run the preprocessor first and only deliver the C/C++ parse tree)</p>
